If you need a good cry this Sunday, look no further than Kristen Wiig holding back her own tears as she dances with each of her cast mates in turn to Mick Jagger singing "She's a Rainbow." Another era of SNL fades away, just in time for the desultory amble of summer. Don't mourn Wiig's departure too long, though — she's probably going to make some awesome movies now that she doesn't have to pantomime Michele Bachmann for the American masses. Plus, there's always Stefon, who made a hilarious appearance on the Weekend Update.
